Alright, I chose WebKit for the same reason.

You probably don't want the UI program to be a port as this implies that the

Good point.

I was wondering, in the case the server node is registered, isn't the C port
able to send data without being launched from the server? Maybe there's a
security concern.

Ah, using the ei interface to encode/decode data without going into writing
a C port, right?
